Abstract

A surgical needle includes an elongated needle body defining a longitudinal axis, and having a main shaft, a needle end adjacent the main shaft, and a needle tip extending from the needle end and having an extreme needle point. The needle end includes a plurality of concave surfaces extending from the needle tip to the main shaft. The needle tip includes a plurality of concave surfaces extending from the needle point to intersect the concave surfaces o f the needle end. The concave surfaces of the needle end are obliquely arrange d relative to the longitudinal axis at a first angle. The concave surfaces of the needle tip are obliquely arranged relative to the longitudinal axis at a second angle greater than the first angle. The elongated needle body include s cutting edges disposed along lines of intersection of the concave surfaces o f the needle end with the concave surfaces of the needle tip. The needle end includes four intersecting concave surfaces and defines a generally diamond- shape in cross-section along an axis transverse to the longitudinal axis. Th e needle end defines a maximum cross-sectional dimension greater than a corresponding maximum cross-sectional dimension of the main shaft. The needl e tip may include four intersecting concave surfaces and define a general diamond shape cross-section.
